How research worksThis market will resolve to "Yes" if Karoline Leavitt says the listed term during the next White House press briefing she participates in. Otherwise, the market will resolve to "No". Any usage of the term regardless of context will count toward the resolution of this market. Pluralization/possessive of the term will count toward the resolution of this market, however other forms will NOT count. Instances where the term is used in a compound word will count regardless of context (e.g. joyful is not a compound word for "joy," however "killjoy" is a compounding of the words "kill" and "joy"). If no such press briefing happens by December 31, 2025, 11:59 PM ET, this market will resolve to "No". If Leavitt ceases to be White House press secretary for any length of time by December 31, 2025, 11:59 PM ET, this market will resolve to "No". The resolution source will be video and transcripts of the press briefing.
